You can connect to the C$ share on your Hyper-V R2 server just like you would any other Windows server. I've got a drive mapped to the C$ share on my Hyper-V R2 Server right now.
By default the VHD's are kept in the Users\Public\Public Documents\Hyper-V\Virtual Hard Disks\ folder, unless you've configured the server otherwise.
I move VHD's to and from this server all the time using this method.

Hello,
Unfortunately it is not possible to backup your virtual pc's while controlling them.
Microsoft recently released a free tool which lets you backup your virtual servers in hyper-v.
This application is called "Windows Server Backup" .
To make this application work smoothly with Hyper-V you will have to get a fix from Microsoft.
"To have us register the Microsoft Hyper-V VSS writer with Windows Server Backup for you, go to the "Fix it for me" section. To register the Microsoft Hyper-V VSS writer with Windows Server Backup yourself, go to the "Let me fix it myself" section."
Link to fix: http://go.microsoft.com/?l
If you however plan to do this yourself, you will have to edit your registry.
To register the Hyper-V VSS writer with Windows Server Backup, follow these steps:
Click Start, click Run, type regedit, and then click OK.
Locate the following registry key:
HKEY_LOCAL_MACHINE\SOFTWAR
Right-click CurrentVersion, point to New, and then click Key.
Type WindowsServerBackup, and then press ENTER.
Right-click WindowsServerBackup, point to New, and then click Key.
Type Application Support, and then press ENTER.
Right-click Application Support, point to New, and then click Key.
Type {66841CD4-6DED-4F4B-8F17-F
Right-click {66841CD4-6DED-4F4B-8F17-F
Type Application Identifier, and then press ENTER.
Right-click Application Identifier, and then click Modify.
In the Value data box, type Hyper-V, and then click OK.
On the File menu, click Exit.
Instructions for backing up the virtual machines by using Windows Server Backup
When you perform a backup of the virtual machines, you must back up all volumes that host files for the virtual machine. For example, if the virtual machine configuration files are stored on the D: volume, and the virtual machine virtual hard disk (VHD) files are stored on the E: volume, you must back up both the D: and E: volumes.
Virtual machines that do not have Integration Services installed will be put in a saved state while the VSS snapshot is created.
Virtual machines that are running operating systems that do not support VSS, such as Microsoft Windows 2000 or Windows XP, will be put in a saved state while the VSS snapshot is created.
Virtual machines that contain dynamic disks must be backed up offline.
Restore virtual machines by using Windows Server Backup
To restore the virtual machines, follow these steps:
Start Windows Server Backup in Administrative Tools.
On the Actions menu, click Recover.
Select the server that you want to recover data from, and then click Next.
Select the date and time that you want to restore from, and then click Next.
Select the Applications recovery type, and then click Next.
Select Hyper-V, and then click Next.
Select the restore location, and then click Next.
Click Recover to start the restore process.
Note All volumes that host files for the virtual machine will be restored. Individual virtual machines cannot be restored by using Windows Server Backup.
Virtual machines that contain two or more snapshots will not be restored. To work around this issue, follow these steps:
Start Hyper-V Manager in Administrative Tools.
Delete the virtual machine that was not restored.
Start Windows Server Backup in Administrative Tools.
On the Actions menu, click Recover.
Select the server that you want to recover data from, and then click Next.
Select the date and time that you want to restore from, and then click Next.
Select the Files and folders recovery type, and then click Next.
Select the directory where the snapshots are stored, and then click Next.
Note By default, the snapshots are located in the following directory:
C:\ProgramData\Microsoft\W
Select the location where the snapshots should be restored, and then click Next.
Click Recover to start the restore process.
After the restore has finished, perform another restore. However, use the Applications recovery type, and select Hyper-V to correctly restore the virtual machines.
Hope this works out,
